Locality bound for effective four-dimensional action of domain-wall fermion
نویسنده
چکیده
We discuss locality in the domain-wall QCD through the effective four-dimensional Dirac operator which is defined by the transfer matrix of the five-dimensional Wilson fermion. We first derive an integral representation for the effective operator, using the inverse five-dimensional Wilson-Dirac operator with the anti-periodic boundary condition in the fifth direction. Exponential bounds are obtained from it for gauge fields with small lattice field strength. e-mail address: [email protected]

Aspects of domain-wall fermions on the lattice
I derive the generating functional for n-point Green’s function of the effective fermion (quark) fields in domain-wall fermions, and clarify the issues pertainent to finite Ns and the lattice spacing a5 in the fifth dimension. These issues can be examined by computing the index, the axial anomaly, and the fermion determinant of the effective lattice Dirac operator, in 2D abelian background gaug...
متن کاملAnomaly cancellation in 2+1 dimensions in the presence of a domain wall mass.
A Fermion in 2+1 dimensions, with a mass function which depends on one spatial coordinate and passes through a zero ( a domain wall mass), is considered. In this model, originally proposed by Callan and Harvey, the gauge variation of the effective gauge action mainly consists of two terms. One comes from the induced Chern-Simons term and the other from the chiral fermions, bound to the 1+1 dime...
متن کاملDomain wall fermion and CP symmetry breaking
We examine the CP properties of chiral gauge theory defined by a formulation of the domain wall fermion, where the light field variables q and q̄ together with Pauli-Villars fields Q and Q̄ are utilized. It is shown that this domain wall representation in the infinite flavor limit N = ∞ is valid only in the topologically trivial sector, and that the conflict among lattice chiral symmetry, strict ...
متن کاملDomain wall fermion and chiral gauge theories on the lattice with exact gauge invariance
We discuss how to construct anomaly-free chiral gauge theories on the lattice with exact gauge invariance in the framework of domain wall fermion. Chiral gauge coupling is realized by introducing a five-dimensional gauge field which interpolates between two different four-dimensional gauge fields at boundaries. The five-dimensional dependence is compensated by a local and gauge-invariant counte...
متن کاملPerturbative study for domain-wall fermions in 4+1 dimensions.
We investigate a U(1) chiral gauge model in 4+1 dimensions formulated on the lattice via the domain-wall method. We calculate an effective action for smooth background gauge fields at a fermion one loop level. From this calculation we discuss properties of the resulting 4 dimensional theory, such as gauge invariance of 2 point functions, gauge anomalies and an anomaly in the fermion number curr...
